Abstract
BACKGROUND Although the incidence of solid pseudopapillary neoplasm (SPN) is <2% of the incidence of pancreatic tumor, the prevalence seems to be increasing. SPNs are mostly benign. However, they also show malignant features. This study aimed to identify the clinical outcomes of patients who underwent surgery for SPN at a single center. METHODS Data on 217 patients with SPN who underwent surgery in Samsung Medical Center between 2000 and 2020 were retrospectively analyzed. RESULTS Herein, the mean age of the 217 patients was 40.0 ± 12.6 years, with a female predominance (80.6%). Most patients had no comorbidity. The mean tumor size was 4.4 ± 3.1 cm. The tumor was located at the pancreatic head in 36 patients (16.6%), the body of the pancreas in 69 patients (31.8%), and the pancreatic tail in 96 patients (44.2%). Of note, 35 patients (16.1%) underwent pancreaticoduodenectomies, 148 patients (68.2%) had distal pancreatectomies, and the other patients had subtotal /total pancreatectomy (9.7%) or enucleation/mass excision (6.0%). No patient had lymph node (LN) metastasis. Moreover, 6 patients (2.8%) had a recurrence in the liver or regional LNs. The 5-year recurrence-free survival rate was 96.8%. The only factor affecting recurrence was tumor size (P = .007). CONCLUSION Because SPN predominates in relatively young women, patients often hesitate to undergo surgery. Nevertheless, as size is the prognostic factor, early resection is recommended for a better prognosis in the case of surgically feasible, young age, and healthy patients.

Abstract
BACKGROUND Margin status is one of the most significant prognostic factors after curative surgery for middle bile duct (MBD) cancer. Bile duct resection (BDR) is commonly converted to pancreaticoduodenectomy (PD) to achieve R0 resection. Additionally, adjuvant treatment is actively performed after surgery to improve survival. However, the wider the range of surgery, the higher the chance of complications; this, in turn, makes adjuvant treatment impossible. Nevertheless, no definitive surgical strategy considers the possible complication rates and subsequent adjuvant treatment. We aimed to investigate the appropriate surgical type considering the margin status, complications, and adjuvant treatment in MBD cancer. MATERIALS AND METHODS From 2008 to 2017, 520 patients diagnosed with MBD cancer at the Samsung Medical Center were analyzed retrospectively according to the operation type, margin status, complications, and adjuvant treatment. The R1 group was defined as having a carcinoma margin. RESULTS The 5-year survival rate for patients who underwent R0 and R1 resection was 54.4% and 33.3%, respectively (p = 0.131). Prognostic factors affecting the overall survival were the age, preoperative CA19-9 level, T stage, and N stage, but not the operation type, margin status, complications, or adjuvant treatment. The complication rates were 11.5% and 29.8% in the BDR and PD groups, respectively (p < 0.001). We observed no significant difference in the adjuvant treatment ratio according to complications (p = 0.675). Patients with PD who underwent R0 resection and could not undergo chemotherapy because of complications reported better survival rates than those with BDR who underwent R1 resection after adjuvant treatment (p = 0.003). CONCLUSION The survival outcome of patients with R1 margins who underwent BDR did not match those with R0 margins after PD, even after adjuvant treatment. Due to improvements in surgical techniques and the ability to resolve complications, surgical complications exert a marginal effect on survival. Therefore, surgeons should secure R0 margins to achieve the best survival outcomes.

Abstract
Margin positivity after hilar resection (HR) for bile duct cancer is commonly observed due to its longitudinal spread along the subepithelial plane; nevertheless, we cannot draw conclusions regarding the prognostic effects of margins with high-grade dysplasia (HGD) or carcinoma. We aimed to investigate the oncologic effect according to the margin status after HR, particularly between the R1 HGD and the R1 carcinoma. From 2008 to 2017, 149 patients diagnosed with mid-bile duct cancer in Samsung Medical Center, South Korea, were divided according to margin status after HR and retrospectively analyzed. Recurrence patterns were also analyzed between the groups. There were 126 patients with R0 margins, nine with R1 HGD, and 14 with R1 carcinoma. The mean age of the patients was 68.3 (±8.1); most patients were male. The mean age was higher in R1 carcinoma patients than in R1 HGD and R0 patients (p = 0.014). The R1 HGD and R1 carcinoma groups had more patients with a higher T-stage than R0 (p = 0.079). In univariate analysis, the prognostic factors affecting overall survival were age, T- and N-stage, CA19-9, and margin status. The survival rate of R0 was comparable to that of R1 HGD, but the survival rate of R0 was significantly better compared to R1 carcinoma (R0 vs. R1 HGD, p = 0.215, R0 vs. R1 carcinoma, p = 0.042, respectively). The recurrence pattern between the margin groups did not differ significantly (p = 0.604). Extended surgery should be considered for R1 carcinoma; however, in R1 HGD, extended operation may not be necessary, as it may achieve oncologic outcomes similar to R0 margins with HR.

Abstract
Subjecting a physical system to extreme conditions is one of the means often used to obtain a better understanding and deeper insight into its organization and structure. In the case of the atomic nucleus, one such approach is to investigate isotopes that have very different neutron-to-proton (N/Z) ratios than in stable nuclei. Light, neutron-rich isotopes exhibit the most asymmetric N/Z ratios and those lying beyond the limits of binding, which undergo spontaneous neutron emission and exist only as very short-lived resonances (about 10-21 s), provide the most stringent tests of modern nuclear-structure theories. Here we report on the first observation of 28O and 27O through their decay into 24O and four and three neutrons, respectively. The 28O nucleus is of particular interest as, with the Z = 8 and N = 20 magic numbers1,2, it is expected in the standard shell-model picture of nuclear structure to be one of a relatively small number of so-called 'doubly magic' nuclei. Both 27O and 28O were found to exist as narrow, low-lying resonances and their decay energies are compared here to the results of sophisticated theoretical modelling, including a large-scale shell-model calculation and a newly developed statistical approach. In both cases, the underlying nuclear interactions were derived from effective field theories of quantum chromodynamics. Finally, it is shown that the cross-section for the production of 28O from a 29F beam is consistent with it not exhibiting a closed N = 20 shell structure.

Abstract
Ascaris lumbricoides causes one of the most common soil-transmitted helminthiases globally. The worms mostly infect the human small intestine and elicit negligible or nonspecific symptoms, but there are reports of extraintestinal ectopic ascariasis. We describe a rare case of biliary ascariasis mistaken for biliary stent in a 72-year-old female patient with a history of liver resection. She visited our outpatient clinic complaining of right upper quadrant pain and fever for the past week. She had previously undergone left lateral sectionectomy for recurrent biliary and intrahepatic duct stones 2 years ago. Besides mildly elevated gamma-glutamyl transferase levels, her liver function tests were normal. Magnetic resonance cholangiopancreatography revealed a linear filling defect closely resembling an internal stent from the common bile duct to the right intrahepatic bile duct. A live female A. lumbricoides adult worm was removed by endoscopic retrograde cholangiopancreatography (ERCP). Despite a significant decrease of the ascariasis prevalence in Korea, cases of biliary ascariasis are still occasionally reported. In this study, a additional case of biliary ascariasis, which was radiologically misdiagnosed as the biliary stent, was described in a hepatic resection patient by the worm recovery with ERCP in Korea.

Abstract
Diamond Blackfan Anemia (DBA) is a congenital bone marrow failure syndrome associated with ribosomal gene mutations that lead to ribosomal insufficiency. DBA is characterized by anemia, congenital anomalies, and cancer predisposition. Treatment for DBA is associated with significant morbidity. Here, we report the identification of Nemo-like kinase (NLK) as a potential target for DBA therapy. To identify new DBA targets, we screen for small molecules that increase erythroid expansion in mouse models of DBA. This screen identified a compound that inhibits NLK. Chemical and genetic inhibition of NLK increases erythroid expansion in mouse and human progenitors, including bone marrow cells from DBA patients. In DBA models and patient samples, aberrant NLK activation is initiated at the Megakaryocyte/Erythroid Progenitor (MEP) stage of differentiation and is not observed in non-erythroid hematopoietic lineages or healthy erythroblasts. We propose that NLK mediates aberrant erythropoiesis in DBA and is a potential target for therapy. Diamond Blackfan Anemia (DBA) is a congenital bone marrow failure syndrome that is associated with anemia. Here, the authors examine the role of Nemo-like kinase (NLK) in erythroid cells in the pathogenesis of DBA and as a potential target for therapy.

Abstract
Detailed spectroscopy of the neutron-unbound nucleus ^{28}F has been performed for the first time following proton/neutron removal from ^{29}Ne/^{29}F beams at energies around 230 MeV/nucleon. The invariant-mass spectra were reconstructed for both the ^{27}F^{(*)}+n and ^{26}F^{(*)}+2n coincidences and revealed a series of well-defined resonances. A near-threshold state was observed in both reactions and is identified as the ^{28}F ground state, with S_{n}(^{28}F)=-199(6) keV, while analysis of the 2n decay channel allowed a considerably improved S_{n}(^{27}F)=1620(60) keV to be deduced. Comparison with shell-model predictions and eikonal-model reaction calculations have allowed spin-parity assignments to be proposed for some of the lower-lying levels of ^{28}F. Importantly, in the case of the ground state, the reconstructed ^{27}F+n momentum distribution following neutron removal from ^{29}F indicates that it arises mainly from the 1p_{3/2} neutron intruder configuration. This demonstrates that the island of inversion around N=20 includes ^{28}F, and most probably ^{29}F, and suggests that ^{28}O is not doubly magic.

Abstract
IntroductionA systematic review of studies related to the psychological characteristics of Sasang typology, a traditional Korean personalized medicine utilizing acupuncture and medical herbs, was conducted with the goal of delineating generalizable psychological profiles of each types using western academic traditions.MethodsJournal articles were collected using 5 electronic database systems in the United States and Korea, and 21 peer reviewed research articles with psychometric inventories were included. Due to the heterogeneity of the studies, the present study sought to report the mutual relevance of the studies based on research results pertaining to the correlation between psychological assessment instruments.ResultsResults of the review indicate that two super-factors of Eysenck, Extraversion and Neuroticism, serve as the foundation in regards to delineating personality constructs, such that the So-Yang type scored high on the Extraversion dimension and low on the Neuroticism dimension compared to the So-Eum type. Current studies with Cloninger's Temperament and Character Inventory also showed that the Novelty Seeking and the Harm Avoidance can be related to the So-Yang and the So-Eum type, respectively.ConclusionsThe present systematic review indicates that Neo-Confucianism-based Sasang typology shares similarities with the western psychological tradition. There is an urgent need to study similarities and differences between both of them in multiple perspectives including mechanism of action beneath the medical intervention. The Bio-psycho-social basis of the Sasang typology can guide us to the temperament-based personalized integrative medicine covering western orthodox and traditional oriental medicine.

Abstract
ObjectivesPersonality was shown to play an important role for well being under academic stress. The purpose of the present study was to evaluate how temperament and character traits predict academic burnout in Korean medical students.MethodsOne hundred and seventy-eight Korean medical students completed the Cloninger's temperament and character inventory (TCI) at the beginning of semester and Maslach burnout inventory-student survey (MBI-SS) was also measured around the final exam when academic stress and burnout is at the highest. The correlation between TCI and MBI-SS was examined and stepwise regression analysis was performed to measure how well personality traits predict academic burnout level.ResultsThe MBI-SS total burnout score was correlated positively with harm-avoidance (r = 0.247, P < 0.05) and negatively with self-directedness (r = -0.296, P < 0.001) and Cooperativeness (r = -0.169, P < 0.05) scores. The regression analysis showed that the harm-avoidance (β = 0.269, P < 0.001) accounted for exhaustion score and the self-directedness explained the Total burnout score (β = -0.296, P < 0.001) and Inefficacy score (β = -0.284, P < 0.001). The Cynicism score was accounted for high Novelty-Seeking (β = 0.150, P < 0.05) and low Cooperativeness (β = -0.182, P < 0.05).ConclusionThis study showed that the Cloninger's temperament and character might explain the burnout level from the stressful medical education. The temperament of novelty-seeking and harm-avoidance could provide the susceptibility to the academic burnout and the character of self-directedness and cooperativeness might determine the resilience to the negative influence of academic stress.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Corneal dystrophy typically refers to a group of rare hereditary disorders with a heterogeneous genetic background. A comprehensive molecular genetic analysis was performed to characterize the genetic spectrum of corneal dystrophies in Korean patients. Patients with various corneal dystrophies underwent thorough ophthalmic examination, histopathologic examination, and Sanger sequencing. A total of 120 probands were included, with a mean age of 50 years (SD = 18 years) and 70% were female. A total of 26 mutations in five genes (14 clearly pathogenic and 12 likely pathogenic) were identified in 49 probands (41%). Epithelial-stromal TGFBI dystrophies, macular corneal dystrophy and Schnyder corneal dystrophy (SCD) showed 100% mutation detection rates, while endothelial corneal dystrophies showed lower detection rates of 3%. Twenty six non-duplicate mutations including eight novel mutations were identified and mutations associated with SCD were identified genetically for the first time in this population. This study provides a comprehensive characterization of the genetic aberrations in Korean patients and also highlights the diagnostic value of molecular genetic analysis in corneal dystrophies.

Abstract
The aim of this study was to describe the mutational characteristics in Korean hereditary spherocytosis (HS) patients. Relevant literatures including genetically confirmed cases with well-documented clinical summaries and relevant information were also reviewed to investigate the mutational gene- or domain-specific laboratory and clinical association. Twenty-five HS patients carried one heterozygous mutation of ANK1 (n = 13) or SPTB (n = 12) but not in SPTA1, SLC4A1, or EPB42. Deleterious mutations including frameshift, nonsense, and splice site mutations were identified in 91% (21/23), and non-hotspot mutations were dispersed across multiple exons. Genotype-phenotype correlation was clarified after combined analysis of the cases and the literature review; anemia was most severe in HS patients with mutations on the ANK1 spectrin-binding domain (p < 0.05), and SPTB mutations in HS patients spared the tetramerization domain in which mutations of hereditary elliptocytosis and pyropoikilocytosis are located. Splenectomy (17/75) was more frequent in ANK1 mutant HS (32%) than in HS with SPTB mutation (10%) (p = 0.028). Aplastic crisis occurred in 32.0% of the patients (8/25; 3 ANK1 and 5 SPTB), and parvovirus B19 was detected in 88%. The study clarifies ANK1 or SPTB mutational characteristics in HS Korean patients. The genetic association of laboratory and clinical aspects suggests comprehensive considerations for genetic-based management of HS.

Abstract
miRNA is known to regulate up to several hundreds coding genes, thus the integrated analysis of miRNA and mRNA expression data is an important problem. Unfortunately, the integrated analysis is challenging since it needs to consider expression data of two different types, miRNA and mRNA, and target relationship between miRNA and mRNA is not clear, especially when microarray data is used. Fortunately, due to the low sequencing cost, small RNA and RNA sequencing are routinely processed and we may be able to infer regulation relationships between miRNAs and mRNAs more accurately by using sequencing data. However, no method is developed specifically for sequencing data. Thus we developed PlantMirnaT, a new miRNA-mRNA integrated analysis system. To fully leverage the power of sequencing data, three major features are developed and implemented in PlantMirnaT. First, we implemented a plant-specific short read mapping tool based on recent discoveries on miRNA target relationship in plant. Second, we designed and implemented an algorithm considering miRNA targets in the full intragenic region, not just 3' UTR. Lastly but most importantly, our algorithm is designed to consider quantity of miRNA expression and its distribution on target mRNAs. The new algorithm was used to characterize rice under drought condition using our proprietary data. Our algorithm successfully discovered that two miRNAs, miRNA1425-5p, miRNA 398b, that are involved in suppression of glucose pathway in a naturally drought resistant rice, Vandana.

Abstract
Fanconi anemia (FA) is a rare disorder characterized by physical abnormalities, bone marrow failure (BMF), increased risk of malignancies, and cellular hypersensitivity to DNA cross-linking agents. This study evaluated the genetic alterations in three major Fanconi genes (FANCA, FANCC, and FANCG) in 30 FA patients using multiplex ligation-dependent probe amplification and direct sequencing. Thirteen BMF patients were genetically classified as FA-A (n = 6, 46%) and FA-G (n = 7, 54%). Four common founder mutations were identified and included two FANCA mutations (c.2546delC and c.3720_3724delAAACA) and two FANCG mutations (c.307+1G>C and c.1066C>T), which had previously been commonly observed in a Japanese FA population. We also detected four novel deleterious mutations: c.2778+1G>C and c.3627-1G>A of FANCA, and c.1589_1591delATA and c.1761-1G>A of FANCG. This study shows that mutations in FANCA and FANCG are common in Korean FA patients and the existence of four common founder mutations in an East Asian FA population. Mutation screening workflow that includes these common mutations may be useful in the creation of an international database, and to better understand the ethnic characteristics of FA.

Abstract
Dystrophic epidermolysis bullosa (DEB) is an inherited skin fragility disorder that presents various clinical manifestations. DEB is characterized by separation of sublamina densa tissue and abnormalities in the anchoring fibrils that result from mutations in COL7A1 and subsequent defects in type VII collagen. A 16-month-old boy was diagnosed with Hallopeau-Siemens recessive DEB on the basis of typical skin lesions composed of multiple blisters with moderately healed erosions, scarring on trauma-exposed body sites, including hands and feet, pseudosyndactyly and flexion contractures of the toes, and severely dystrophic nails on the right hand. Genomic DNA from the patient and parents were subjected to direct sequencing for the COL7A1 gene. Two heterozygous mutations were detected in the affected child; one novel mutation designated c.4232delC in exon 38 and a single-base substitution (c.6573+1G>C) in intron 81. Deletion of a single cytosine at codon 1411 within exon 38 had produced a frameshift mutation that created a stop codon at codon 1427 (p.Pro1411Leufs*17). This intronic base substitution had led to aberrant splicing and a premature termination codon. This is a novel mutation of COL7A1 associated with DEB in a Korean patient, adding to the range of COL7A1 mutations related to DEB.

Abstract
INTRODUCTION Plasmodium vivax malaria is one of the most important infectious diseases plaguing humanity and causes significant mortality and morbidity worldwide. The gold standard of P. vivax malaria diagnosis is the microscopy of blood smears. Although microscopy is a rapid, cost-effective, and readily applicable method, it has many disadvantages, including low sensitivity, specificity, and precision. Therefore, there is a clear need for an effective screening test for P. vivax malaria detection both in high-prevalence areas and developed countries. METHODS A total of 1761 complete blood count (CBC) samples generated by the automated hematology analyzer (DxH 800™; Beckman Coulter Inc., Miami, FL, USA) were retrospectively analyzed. The sample pool contained 123 samples from 52 P. vivax malaria patients and 1504 nonmalarial samples including 509 patients with leukopenia (white blood cell <2000/μL) and 134 normal subjects. RESULTS The P. vivax malaria samples exhibited easily recognizable typical malaria signals on the nucleated red blood cell (nRBC) plots (sensitivity 100%) in DxH 800™. All 1504 samples without P. vivax infection were negative for malaria signal (specificity 100%). The size of P. vivax malaria signals correlated roughly with the parasite burden. CONCLUSION DxH800™ provides very sensitive and specific, easily recognizable P. vivax malaria signals on routine CBC without need for the additional reagents or special procedures.

Abstract
AIMS To isolate an antagonist for use in the biological control of phytopathogenic fungi including Colletotrichum gloeosporioides, then to purify and characterize the biocontrol agent produced by the antagonist. METHODS AND RESULTS Bacteria that exhibited antifungal activity against the causative agent pepper anthracnose were isolated from soil, with Bacillus thuringiensis CMB26 showing the strongest activity. A lipopeptide produced by B. thuringiensis CMB26 was precipitated by adjusting the pH 2 with 3 n HCl and extracted using chloroform/methanol (2:1, v/v) and reversed-phase HPLC. The molecular weight was estimated as 1447 Da by MALDI-TOF mass spectrometry. Scanning electron and optical microscopies showed that the lipopeptide has activity against Escherichia coli O157:ac88, larvae of the cabbage white butterfly (Pieris rapae crucivora) and phytopathogenic fungi. The lipopeptide had cyclic structure and the amino acid composition was L-Glu, D-Orn, L-Tyr, D-allo-Thr, D-Ala, D-Val, L-Pro, and L-Ile in a molar ratio of 3:1:2:1:1:2:1:1. The purified lipopeptide showed the same amino acid composition as fengycin, but differed slightly in fatty acid composition, in which the double bond was at carbons 13-14 (m/z 303, 316) and there was no methyl group. CONCLUSION A lipopeptide was purified and characterized from B. thuringiensis CMB26 and found to be similar to the lipopeptide fengycin. This lipopeptide can function as a biocontrol agent, and exhibits fungicidal, bactericidal, and insecticidal activity. SIGNIFICANCE AND IMPACT OF THE STUDY Compared with surfactin and iturin, the lipopeptide from B. thuringiensis CMB26 showed stronger antifungal activity against phytopathogenic fungi. This lipopeptide is a candidate for the biocontrol of pathogens in agriculture.

Abstract
The induction of interleukin-6 (IL-6) using combined proinflammatory agents (LPS/IFN-gamma or TNF-alpha/IFN-gamma) was studied in relation to p38 mitogen-activated protein kinase (MAPK) and NF-kappaB transcriptional factor in primary neonatal cardiomyocytes. When added to cultures of cardiomyocytes, the combined agents (LPS/IFN-gamma or TNF-alpha/IFN-gamma) had stimulatory effect on the production of IL-6 and the elevation was significantly reduced by SB203580, a specific p38 MAPK inhibitor. SB203580 inhibited protein production and gene expression of IL-6 in a concentration-dependent manner. In this study, IFN-gamma enhancement of TNF-alpha-induced NF-kappaB binding affinity as well as p38 MAP kinase activation was observed. However, a specific inhibitor of p38 MAPK, SB203580, had no effect on TNF-alpha/IFN-gamma or LPS/IFN-gamma-induced NF-kappaB activation. This study strongly suggests that these pathways about TNF-alpha/IFN-gamma or LPS/IFN-gamma-activated IL-6 release can be primarily dissociated in primary neonatal cardiomyocytes.

Abstract
Previous reports in the literature concerning cerebrovascular accident have illustrated cases of post-stroke tremor. Treatments of these studies have varied. Trials of levo-dopa have been reported in two such cases. This case study reports on a case of a patient with a left thalamic, left superior cerebellar artery infarction with a lacunar infarction in the basal ganglia. The patient developed a violent tremor/movement disorder which was unresponsive to haloperidol. With this failure, and with the evidence of a basal ganglion lesion, levo-dopa/carbi-dopa was introduced as an intervention. The amplitude of the tremor was dramatically reduced, with protective devices removed, and with complete cessation of the tremor at rest. The medication was withdrawn and reintroduced with a reduction and subsequent resolution of the symptoms. A discussion of the previous studies of movement disorder with cerebrovascular accident is included.

Abstract
BACKGROUND In the surgical repair of tetralogy of Fallot or pulmonary atresia, pulmonary regurgitation may be detrimental in the postoperative period. We have used homograft monocuspid valve patch to prevent pulmonary insufficiency. METHODS From September 1996 to December 1998, twenty-five patients, 4 months to 8 years of age (median 10.1 months) had homograft monocuspid valve in the procedure of right ventricular outflow tract reconstruction. The function of the monocuspid valve was assessed by echocardiogram and graded as trivial to mild, mild to moderate, moderate, and severe. We evaluated the degree of pulmonary insufficiency before discharge, at 3-6 months, and at 12 months after the operation. RESULTS There was one hospital death due to fulminate adeno viral pneumonia. On echocardiogram, 21 patients (88%, 21/24) had no significant pulmonary insufficiency. Only one patient (4.5%) showed a moderate degree of pulmonary insufficiency. At 3-6 months, seventeen of twenty-one (81%) patients had no significant pulmonary insufficiency. There were fourteen patients who had follow-up over 1 year, and no patients showed newly developed significant pulmonary insufficiency. CONCLUSIONS We concluded that the homograft monocuspid valve patch for right ventricular outflow tract reconstruction has provided excellent early results for the prevention of pulmonary insufficiency. However these effects are limited in duration and further close follow-up should be needed.

Abstract
Nuclear factor-kappaB (NF-kappaB) activity affects cell survival in ROS 17/2.8 osteoblasts. Preventing NF-kappaB transcription activity with a potent NF-kappaB inhibitor, pyrrolidine dithiocarbamate (PDTC), results in apoptosis. Thus, we explored the effect of pyrrolidine dithiocarbamate (PDTC), which potently blocks the activation of nuclear factor-kappaB (NF-kappaB) in serum-exposed condition, on the activation of mitogen activated protein kinase (MAPK), especially, JNK/SAPK and p38 MAPK induction. PDTC transiently increased the phosphotransferase activity of c-Jun N-terminal Kinase1 (JNK1), which might in turn activates transcriptional activity of activating protein-1 (AP-1). The activation of JNK was completely decreased in dominant negative JNK1 transfected cells and the PDTC-induced cell death was attenuated in these cells. In addition, AP-1 activation was decreased in the JNK1 transfected cells, compared with vector-transfected cells. The NF-kappaB inhibitor also transiently activates p38 MAPK but SB203580, a specific p38 MAPK inhibitor, does not have any regulatory effect on PDTC-induced cell death, suggesting that the cell death is mediated by JNK not by p38 MAPK. Thus, overall, these results show that PDTC induces apoptosis and suggest that JNK/SAPK and subsequent AP-1 activation may be involved in the apoptotic pathway in ROS 17/2.8 osteoblasts.

Abstract
BACKGROUND Because blebs are confirmed in most of the patients undergoing thoracotomy, identification of blebs by high-resolution computed tomography (HRCT) can be proposed as a surgical indication in primary spontaneous pneumothorax (PSP). If an apical bleb is identified, we treat the patient by video-assisted thoracic surgery (VATS). METHODS From May 1995 to September 1997, 61 patients (21.9 +/- 4.6 years) were seen for initial episodes of PSP. Only seven showed bullae on simple chest radiography. However, by HRCT, 48 had sizable blebs (>5 mm), and 45 were treated surgically by VATS. RESULTS The mean duration of chest tube use after surgery was 3.2 +/- 1.9 days, and the mean hospital stay was 4.5 +/- 1.9 days. Only one recurrence developed 5 weeks after VATS. CONCLUSIONS Our protocol is effective in controlling an initial episode of PSP. It shortens the observation time before definitive surgical treatment, shortens the hospital stay, and decreases the likelihood of recurrence.

Abstract
We experienced an unusual case of cardiac tamponde caused by a rupture of the coronary arteriovenous aneurysm in a 54-year-old woman. The patient was suffered from sudden chest pain and syncope, and was initially managed by pericardiocentesis following an echocardiogram which revealed a massive pericardial effusion with signs of cardiac tamponade. She was referred to our hospital under the impression of aortic dissection with cardiac tamponade. She underwent an emergency operation and was found to have a 2 x 2 cm sized bleeding cystic mass protruding from the proximal anterior descending coronary artery. The aneurysm was excised and the openings connected with the coronary artery and right ventricular outflow tract were closed with sutures from the inside of aneurysm. Subsequent coronary arteriography supported the diagnosis.

Abstract
The technique of cerebral protection during hypothermic circulatory arrest remains controversial. Forty-seven patients underwent operations for type A aortic dissection in the past 9 years. During hypothermic circulatory arrest, selective cerebral perfusion and retrograde cerebral perfusion was applied in 12 and seven patients, respectively. The mortality rate was 28.6% in patients without adjunctive cerebral perfusion, 25.0% in selective cerebral perfusion patients, and zero in the retrograde cerebral perfusion group (P > 0.05). However, there was no mortality by cerebral injury in cerebral perfusion groups (P = 0.03). Age (P = 0.001), hypothermic circulatory arrest time (P = 0.012), and acuity (P = 0.013) were predisposing factors for cerebral injury, but cerebral perfusion has not yet been found to be a protective factor (P = 0.56). Nine late reoperations and three deaths occurred during the follow-up period. Marfan syndrome was the only predisposing factor for late reoperation (P = 0.016). In summary, although further studies are still required, retrograde cerebral perfusion is a possible cerebral protective factor. In addition, periodic follow-up is mandatory, especially in patients with Marfan syndrome.

Abstract
The effects of the selective dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,5,6-tetrahydropyridine (MPTP) on the kinematics of two-dimensional arm movements in the primate were studied. Two rhesus monkeys were trained to move a manipulandum at various distances and directions in horizontal space from a centrally located target box. Several kinematic parameters including reaction time, and time and amplitude of peak tangential velocity were analysed. Following an extensive control evaluation period, the animals were unilaterally injected with MPTP into the internal carotid artery. The animals were restudied for up to 289 days following induction of hemiparkinsonism. Larger-amplitude movements (greater than 3.5 cm) were more severely affected than smaller amplitude movements. Both animals exhibited marked changes in the arm movements including increased time-to-peak velocity and decreased peak velocity. The degree of the kinematic changes was spatially dependent, with the decrease in velocity as well as the time-to-peak velocity being more pronounced for the larger, outward movements. Reaction time increased but showed no spatial dependency. Kinematic deficits persisted over the entire time-period studied. Also, the kinematic changes were reduced by levo-3,4 dihydroxyphenylalanine in a dose-dependent manner. Tyrosine hydroxylase immunohistochemistry documented extensive cell loss in the substantia nigra. These results show that both the timing as well as the amplitude of the velocity profiles are disrupted by MPTP consistent with the known akinesia and bradykinesia of parkinsonism. Although abnormalities were present for all directions and distances, a spatial dependency to the deficits was detected. The observation of more pronounced changes for larger, outward movements suggests a role for the basal ganglia in production of larger-amplitude movements directed away from the body.
